The proposed transmitted frame non-orthogonally superimposes two different waveforms, which are frequency modulated continuous-wave (FMCW) for radar-sensing and orthogonal frequency division multiplexing (OFDM) for communication. Also, the receiver scheme that performs channel estimation via radar-sensing functionality without degrading data rate of communication operation is introduced. As numerically evaluated, the proposed system achieves good ","authors_text":"Huseyin Arslan, Mehmet Mert Sahin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2020-07-11T11:56:11Z","title":"Multi-functional Coexistence of Radar-Sensing and Communication Waveforms"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2007.05753","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:98dcfa6347d63131d0867caff29b0ef3a7d860107e7c2d7ae6e6263b5bd6c309","target":"record","created_at":"2026-07-05T01:18:06Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"91145906ee4fe970ab373df5cd5203a425252ffa1d173f2219f2ad506fb0ecf2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2020-07-11T11:56:11Z","title_canon_sha256":"e65bb8ecd37d4faa67d8d7848b52319396781d8034a30b28fb0ccb0d843d30b7"},"schema_version":"1.0","source":{"id":"2007.05753","kind":"arxiv","version":1}},"canonical_sha256":"0a5dc8d306c19f64fa277775194f9082d11bad084d2485621be30f5895663777","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0a5dc8d306c19f64fa277775194f9082d11bad084d2485621be30f5895663777","first_computed_at":"2026-07-05T01:18:06.485035Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:18:06.485035Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"22WX6nkn1MNnKioY/EOeMSPUdwD/BVT05L5H5F238MXwNJt3uqoi/dmubbFFnhpTg9aAIjNWWiuRgS2uy8QoCw==","signature_status":"signed_v1","signed_at":"2026-07-05T01:18:06.485450Z","signed_message":"canonical_sha256_bytes"},"source_id":"2007.05753","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:98dcfa6347d63131d0867caff29b0ef3a7d860107e7c2d7ae6e6263b5bd6c309","sha256:75f22ae21cf928e717687f39776ecfdb57f3bd7051792425afa5a7b2d1827373"],"state_sha256":"772ad4ce2c1abbb7225bb166743d902ab0be211c7b8dc4c59379694e9f22e5fd"}
